KAWASAKI, Japan--(BUSINESS WIRE)--Jan 21, 2025--
Toshiba Electronic Devices & Storage Corporation ("Toshiba") has introduced seven 32-bit microcontrollers equipped with the Cortex-M4 core, expanding its extensive lineup of motor control microcontrollers. Six products constitute a new group, M4K group(1) [1], while one joins M470 group.
This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20250121621097/en/
The maximum operating frequency of the M4K group(1) microcontrollers is 120MHz, and 160MHz for M470 group. All are equipped with two motor control functions. In addition, like current products in both M4K group and M470 group, they are equipped with encoder interfaces and programmable motor control functions, which reduce CPU loads during motor control. They also inherit the checking mechanism for flash memory, RAM, AD converter and clock, and can be used for self-diagnosis functions. Sample programs, which will be used to obtain IEC 60730 Class B functional safety certification, are also provided to contribute to developing motor driven components for consumer and industrial equipment.
Current M470 group products have a maximum flash memory capacity of 512KB. The new addition to the M470 group boosts this to 1MB while still maintaining up to 100,000 program/erase cycles, supporting device functionality enhancements. Incorporation of a FOTA [2] function satisfies increasing needs for IoT support.
Along with samples, documentation, sample software, evaluation boards, and driver software with control interfaces for peripheral functions are available for use in preliminary evaluation. Development environments are provided in cooperation with ARM global ecosystem partners.
Notes
[1] Equipped with Arm Cortex-M4 (FPU function) core, maximum operating frequency 120MHz; equipped with motor control function, can control up to 2 motors.
[2] FOTA: Firmware update Over The Air
Applications

NEW YORK (AP) — Financial markets are moving cautiously Thursday, a day after surging on optimism about a ceasefire in the war with Iran, and U.S. stocks are rising even though oil prices are too.
The morning began with modest losses for Wall Street, following up on slides across much of Asia and Europe. But the S&P 500 erased its dip and was up by 0.5% in midday trading after Israel said it would begin direct negotiations with Lebanon “as soon as possible.” That calmed some of the worries that the two-week ceasefire announced late Tuesday could already be in trouble because of Israel's bombardment of Lebanon.
The Dow Jones Industrial Average was up by 238 points, or 0.5%, as of 12:15 p.m. Eastern time, and the Nasdaq composite was 0.7% higher after both indexes also erased early losses.
Oil prices pared some of their gains, but they nevertheless remained higher on the day after semiofficial news agencies in Iran suggested forces have mined the Strait of Hormuz. The narrow waterway has been at the center of President Donald Trump’s demands of Iran, and blockages there have kept oil and natural gas stuck in the Persian Gulf, away from customers worldwide.
The price for a barrel of benchmark U.S. crude rose 4% to $98.18. Brent crude, the international standard, added 1.1% to $95.79 per barrel. It’s still below the $119 level that it briefly reached when worries about the war reached their height, but it remains above its roughly $70 level from before the war.
Given how far apart the United States and Iran seem to be in their demands, upward pressure on oil prices may be “here to stay for a while” according to strategists at Macquarie led by Thierry Wizman. Risks remain for renewed fighting, which could cause customers worldwide to hoard whatever oil supplies they do get. That could itself keep oil off the market, much like actual fighting targeting pipelines or oil tankers.
On Wall Street, Constellation Brands climbed 6.5% for one of the market's bigger gains after reporting stronger results for the latest quarter than analysts expected. The company, which sells Modelo beer and Robert Mondavi wines, said it saw encouraging trends heading into its new fiscal year. But it pulled its financial forecasts for the following fiscal year because of “limited near-term visibility” and other factors.
CoreWeave rallied 4.3% after announcing an expanded, $21 billion deal with Meta Platforms to provide AI cloud capacity through December 2032. Meta rose 3.8%.
On the losing end of Wall Street was Simply Good Foods, which sank 19.5% after reporting a worse drop in revenue than analysts expected. CEO Joe Scalzo called the results unsatisfactory and said the company behind the Quest and Atkins brands is making immediate changes to turn around its performance.
A suite of mixed reports on the U.S. economy also helped to keep Wall Street in check. One said an underlying measure of inflation that the Federal Reserve considers important was slightly hotter in February than economists expected. It decelerated before the war with Iran began, but not by as much as economists expected.
A separate report said that more U.S. workers applied for unemployment benefits last week than economists expected. The number was not very high compared with history, but it could indicate an acceleration in layoffs.
Treasury yields swiveled up and down in the bond market following the reports, and the yield on the 10-year Treasury edged down to 4.27% from 4.29% late Wednesday.
The 10-year yield, though, remains well above its 3.97% level from before the war, which has sent rates up for mortgages and other kinds of loans going to U.S. households and businesses.
If oil prices stay high and keep upward pressure on inflation, the Federal Reserve would have difficulty resuming its cuts to interest rates to help the slowing economy, even if the job market weakens. A growing number of Fed officials seem to be considering the possibility of a hike in rates, according to minutes of their latest meeting released on Wednesday.
In stock markets abroad, South Korea’s Kospi fell 1.6%, and Germany’s DAX lost 1.1% for two of the world’s biggest moves.
